Dear Seth:
1) " ... should be ... ": Instead of "hand
wave", this is a diplomatic expression to challenge the software
engineers' knowledge of the networking program code for the
current case. Ever since we started our study, we were quite
puzzled by why the 240/4 netblock was regarded so special? Why
no one could tell us what led to its current status, and even
after IPv4 was set to transition to IPv6? ... etc. We also could
not find anyone who could describe to us how was it being
handled in the existing programs. This included those who
claimed to be experts in the subject. Perhaps they intentionally
tried to hide the detail, or they also did not know? One day, we
finally came across a program fragment that could perform the
"disabling 240/4 netblock" function. Upon presenting it to an
acquaintance knowledgeable of networking programs, he confirmed
that it was one concise technique to do the job. That was
sufficient for our purpose as system engineers, because we
should not overstep our duties by doing software engineer's
programing task. That is, as long as we can demonstrate that
"there exists" a solution, like proofing a mathematics theorem,
we have completed our part of the deal.
2) " ... discussed to death many times over
... ": This was what we were told when we first looked into
this subject over half a dozen years ago, and more times along
the way. As long as there was an issue not resolved, however,
every angle should be continuously explored. In science and
engineering, if we stopped studying, because of this kind of
viewpoint, we would have missed a lot of inventions and
discoveries. So, this particular consideration is not in our
books.

The cost of this software engineering should be minimal.
So basically no solution is offered to what is the showstopper for this proposal, only a hand wave that it "should be" easy to fix (but that's everyone else's problem). I mean, I believe this has been discussed to death many times over in the past and yet here we still are. ------------------------------
